Boundary lubricating bearings are essential components used in various industries for reducing friction and absorbing vibrations in linear or rotary motion applications. These bushings are designed with a unique grooved structure that offers numerous advantages and distinctive characteristics.

The main features of grooved sliding bushings include:

1. Grooved structure: The bushings are composed of a design with cavities or grooves that promote the retention of lubricant. This structure allows for uniform distribution of lubricant during operation, ensuring effective lubrication and reducing friction.

2. Wear reduction: Thanks to the presence of grooves, grooved sliding bushings reduce wear as the lubricant is trapped inside the voids, minimizing metal-to-metal contact.

3. Vibration absorption: Grooved bushings are capable of absorbing vibrations and mechanical stresses due to their elastic structure and the lubricant trapped in the grooves. This results in quieter operation and increased comfort.

4. Corrosion resistance: Grooved sliding bushings are made with corrosion-resistant materials such as bronze, stainless steel, or other composites, making them suitable for use in aggressive environments.

5. Ease of installation and maintenance: These bushings are designed to be easily installed and replaced, reducing machine downtime. Additionally, they require minimal maintenance due to their ability to retain lubricant for extended periods.

The use of grooved sliding bushings is extensive and extends to various industries, including:

1. Automotive industry: Grooved bushings are used in various automotive components such as suspensions, shock absorbers, linkages, and steering columns to ensure smooth operation and reduce wear.

2. Marine industry: They are employed in maritime applications such as drive shafts, bridge structures, rudders, and engine housings, where corrosion resistance and lubrication efficiency are critical.

3. Aerospace industry: Grooved bushings are used in flight control systems, actuators, landing gear, and other aerospace applications, where lightweight, fatigue resistance, and high performance are essential.

4. Energy industry: They are utilized in turbines, generators, compressors, and other power generation equipment.
